4. Sri O.Manoher Reddy, learned Standing Counsel for the appellants/APSEB would contend that admittedly the Contracted Maximum Demand (C.M.D) is fixed at 15000 KVA and the writ petitioner exceeded the CMD by 1320 KVA during the month of September 1988. He would further contend that as per Clause 7, if in any month the recorded maximum demand of a consumer exceeds the contracted demand by more than 5%, that portion of the demand in excess of the contracted demand and that portion of the proportionate energy will be billed twice the normal charges towards demand, energy and fuel cost adjustment charges; that there is a method in issuing every bill consisting of three components viz., demand, energy and fuel cost adjustment charges; that admittedly the recorded maximum demand exceeded by 5% of the contracted demand and as such the consumer is liable to pay twice the normal charges and that as per the terms and conditions of the contract, the writ petitioner is bound by Clause 7 and unless and until the said clause is held to be illegal or declared as null and void, the writ petitioner is bound to pay twice the normal charges towards demand, energy and fuel cost adjustment charges and, therefore, the bill dated 28-09-1988 was rightly issued.
